The short, expensive tail of the set.
Every S12a: VSTAR Universe card in the moonstone catalog, in collector-number order. Market is the same TCGplayer figure each card page quotes; a dot means we hold no price for that card yet.
You can own 340 of the 350 priced cards in S12a: VSTAR Universe for about $1,023. The median card is $0.57. The remaining $1,247 sits in just 10 chase cards, and one of them (Giratina VSTAR - 261/172, $301) is 13% of the entire set on its own. A full set is not one long climb. It is a cheap, fast 45% and then a very short, very expensive tail.
Computed from this set's own recorded value series; windows are stated and nothing is modeled. Each return is the first recorded value inside its window against the last. We withhold it when the number of cards in the basket changed inside the window, when a single step moved more than 20%, or when the series cannot cover the window.
No published pull-rate study exists for this set, so there is nothing honest to simulate. We only rip sets whose per-pack odds come from a published, sourced study, and an inherited or inferred rate would put an invented number under every figure on this panel.
We publish a rip simulation only where per-pack odds come from a published, sourced study. Which sets have published pull rates counts what exists: 31 of the 110 English sets sold in booster packs, resting on eleven studies.
